T 0 all whom it may concern.

Be it known that 1:, Gnome Vi Ann e lone, a, citizen of the UnitedStates, residing at Ueklend, in the county of Alameda and State ofCalifornia, have invented new and useful Improvements in Journal-Boxes"for Roller-Bearings, of which the following is o specification. I

The present invention is designed particu- I lerly for providing animproved roller been ing journal box for cars in use on streetrailiveys, interurban roads, or

' and the inventionresides essentially in the steam railroads,

utilization of "the" roller bearing device in lieu of the usual solidbearing of this type involving the use of the brass and key been in,elements.

he invention also contemplates an imroved form of oil or lubricant boxor cell inclosing the bearing members about the journal of the axle inorder that the bearing member may be continuously supplied withlubricant or oil and which may be applied to the journal or withdrawntherefrom with facility. Other meritorious features of the inventionwill be described and claimed in the following. specification, and inthe ac.- coznpenying drawings i have illustra ed one complete example ofthe gihysicnl embodiment of my invention, the parts being constructedand combined according to the host mode I have so for devised for theprecticel application of the principles of the inventlon.

Fig. i is a top phm'view of the lohgitudimil roller bearing on top ofthe oil cell or box, parts being omitted.

Fig. 5 is a front detail view of the spout and closure ofthe oil cell.and Fig, 6 is a side view in detail of the spout and closure.

Fig. 7 is a transverse sectional-view oi? the box, bearing and cell, online T--7 of Fig, 1.

Fig. 8 is a longitudinal, sectional view of v the oil cell.

lfn order that the invention. may be readily l have ut1l1zed thestandard form of our journal box 1 which carries the load of the car onits top plate 2 and slides vertically as usual between the guides (notshown) off the underframe of the car. The customary lid 3 and dust guardd are present,

the former to provide access to the interior of the box and the lattersurrounding and protecting the journal end of the side 6. in using thedevice of the invention, the grease and Waste for lubricating andpacking commonly employed, are eliminated, and an oil cell substituted,which is preferably a metallic structure comprising the two sections 7and 8 that are joined b y the removable bolts 9 extending along eachside of the cell and passing through complementary eers 10 similar to nhinge joint, but of course the two bolts hold the sections rigidlytogether. The bolts are passed through the front plate 11, which isscrewed to the cell, and after passing" through the nlined ears l0fu'euded into the last car at the rear of icel and the cell is retainedon the journal through the instrnnientelity of e divided or snap ring"12 that is sprung into an annular groove in the axle COvilClilIltZ; withthe grooved beck piste .13 of the cell, and the rear up- Wei-divproccting flange 1 of the lower section that is similarly grooved to fitover the ring. The bncleplate is screwed'to the upper section of thecell, and these elined, grooved, members form an annular recess for thering 12 to turn in and through these grooved members the ring retainsthe cell against e--:iel movement on the journal. illie front plate llof the cell is fashioned with n. filling spout 15 provided with a closefitting closure or gate 16, pivoted to swing at 17 and equipped with ahandle .18 that springs down behind the receiver or hook 9 of the spout,and through the spout the lubricating oil is provided forthe cell. Aglass plate or Window 520 may be utilized to inspect the interior of theoil cell to ascertain the quantity of lubricant therein, and 7 series ofslots is arranged an intermediate series of slots 23 that arecomparatively longer thanthe end slots and staggered or offset out ofalinement with them.

Through these slots the rollers 24, and 25, protrude, slightly beyondthe outer periphery of the cage or sleeve and associated with the twoseries of end slots and the intermediate slots respectively, the rollersbeing of exactly the same diameter, but difiering in length to lit theslots.

The long bearing rollers 25 are journaled in two intermediate rings 26,26, spaced equidistant between the ends of the cage and also from thelongitudinal center thereof, and the shorter rollers are journaledbetween these intermediate rings and the end rings 27, 27, all therings, four in number,

being secured, as by rivets or screws pass ing through the cage and intothe rings at the interior of the cage.

Preferably the cage is of resilient material, and at its ends the cagemay be divided as at "28, 28, while intermediate divisions 29, 29 mayalso be provided .thus permitting an adjustment oi the annular cageabout the ournal 1n order to secure close. and uniform contact oi therollers with the journal. At the ends of the cage, connecting straps orplates 30, formed with slots 31, are rigidly secured at one end to thedivided ring 27, and the other end of each strap with its slot 31 may besecured to the adjoining end. of the divided ring 27 (see Fig. 3) bymeans of theset screw 32 in the end of the divided ring. Thus all fourof the bearing rings 26, 26, and 27, 27, and-the cage itself, aredivided. and their lines of division co-axial with the journal, so thatthe cage with its rollersl may be adjusted to best position with regardto the journal to secure highest efliciency, and the coupling straps 30,80 will prevent the resiliency of the material of the cage fromspringing it to an excessively open position.

At each endot the top plate 3?, which extends horizontally across the,up per section 7 of thecell, is fashioned a downwardly arrangedcentrally located lug, 34- and 35 which lugs are designed to retain thecage within thecell and preserve its'proper relation within the cell.

In the outer face of each side of the journal boa: cell, near thetop,,is provided a groove 36 extending substantially the fullsuliiciently to free the cell from them .joints are provided on plates14: and 13 reissaaao Oil is supplied to the cell through the spout, upto a normal level just belowthe outer periphery of the journal, and thecell is rendered tight in its joints. to prevent escape of the oil fromthe cell by'overlap ping, downwardly projecting flanges 38 at each sideof the upper section or half of the cell fitting withinthe lower sectionthe rear end ofi the cell. Tongue and groove spectively as indicated bydotted lines 39 and 40 in Fig. 7, and at-the front end by plate ll-w'ithgasket it necessary. Gaskets are provided around the window glass in thefront of the, cell and other necessary pre- 30 cautions may be taken, inthe construction of the cell to prevent escape of oil, as usual. Endthrust and longitudinal movement of the bearing on the journal areprovided for by the presence of two series of rollers 41 and 4-2,located transversely of the journal, between the top plate 33 of thecell and the bearing plate or top plate 2 of the journal box, and areheld in place by side bars is secured to the top of the cell andextending alongthe upper side edges thereof. These two series of rollerscarry the load between the journal and the hearing or top plate the box,and the snap ring 12 retainsthe cell on the journal, as beforeexplained. By this construction and arrangement of parts, the slightestaxial movement of the journal, inwardly or outwardly with relation tothe car, due to rounding curves by the car, worn flanges on the wheels,etc, is absorbed and the limit of movement of the cell before entheoffset position of the rollers the possibility of their balking orjamming when takmg the load is eliminated, and by the same dispositionof parts, they will leave the load without strain.

lln the assemblageot the parts of the de vice, assuming the snap ring 12is in place ,on the journal, the cell is first placed inside the journalbox, in sections, the lower sec-' tion 8 being placed in the bottombelow the journal, and the upper section with the back plate thereomissuspended by its grooves and the screws as explained. The cage withitsrollers isthen sprung over the journal and the two bolts 9 are placedin position and screwed up, and finally the tront'plate 13. is screwedhome.

By the utilization of my improved roller journal bearing and oil box,the usual wool and cotton packing is eliminated, a continuously, wellsupplied luluicant is furnished to the journal and friction is sogreatly rc- (luced that vast,savings in transportation will result.

What Iclaim is- 1. The combination with the journal having a retainingring thereon, of a closed lubricant cell on the journal engaged bj saidring, a cage Within the cell and rollers carried by said cage andinterposed between the cell and journal.

2. The combination with the journal having a retaining ring and alubricant cell ongaged by said ring, of bearing rollers between thejournal and cell, a journal box incasing the cell, and'end thrustbearing rollers between the journal box and cell.
